The John Guest grey push‑fit acetal stem adaptor (NPTF thread) is designed to convert a John Guest push‑fit connection into an NPTF threaded connection. Installation is quick and straightforward—John Guest push‑fit technology provides an instant, secure connection and a leak‑tight seal without the need for tools, heat, or sealing compounds.

Its precision‑engineered collet‑locking mechanism grips the pipe firmly without deforming it or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to enhance system performance and reduce downtime during maintenance.
